# conserver/sbuild.pl -- per-package Ubuntu/Debian builder for conserver-xcat; the apt/sbuild analogue
# of conserver/mockbuild.pl. Builds the package inside the matching <codename>-<arch>-sbuild chroot from
# its MAINTAINED debian/ packaging and collects the .deb(s) into --result-dir. Invoked by sbuild-all.pl
# per (codename,arch); also runnable standalone. Out-of-tree: the build runs on a COPY of the package
# tree (the checkout is never mutated). The common chroot orchestration lives in
# BuildUtils::build_deb_in_chroot; only conserver's source prep + dpkg-buildpackage is below.
